Sangano reUS Environmental Protection Agency riri kuronga kurambidza kushandiswa kwemethylene chloride, kemikari yarinoti inogona kukonzera njodzi kuhutano uye kunyange rufu, kuchengetedza hutano hweveruzhinji.
Chirongwa ichi chaizorambidza kushandiswa kwemethylene chloride mumamiriro ese ezvinhu evatengi uye mumashandisirwo mazhinji emaindasitiri nemabhizimisi. Methylene chloride inoshandiswa mukubvisa mafuta muaerosol, mukuchenesa mabhurashi ekupenda nekupenda, mukubatanidza magiya nezvinonamira zvemabhizimisi, uye mukugadzira mamwe makemikari munzvimbo dzemaindasitiri.
Kurambidzwa uku kwakakurudzirwa sechikamu cheMutemo weToxic Substances Control Act, uyo, pakati pezvimwe zvirambidzo, unopa Environmental Protection Agency simba rekuisa zvinodiwa pakuzivisa, kuchengeta zvinyorwa uye kuyedza. Muna 2019, Environmental Protection Agency yakarambidza mutengi mumwe kushandisa methylene chloride nekubvisa kubva muzvimedu zvependi.
Vanhu vanosvika 85 vakafa nekuda kwekushandisa mushonga uyu kubvira muna 1980, sekureva kweUS Environmental Protection Agency. EPA yakati nyaya zhinji dzine chekuita nevashandi vari pazvibvumirano zvekugadzirisa dzimba. Sangano iri rakati kune nyaya "dzitsva" dzevanhu vari kutambura nezvirwere zvakakomba uye zvinogara kwenguva refu mushure mekushandisa methylene chloride. Environmental Protection Agency yakaratidzawo migumisiro yakaipa pahutano inobva mukufema uye kubata ganda, kusanganisira chepfu yeuropi, migumisiro yechiropa, uye kenza.
Sangano iri rakaona kuti methylene chloride "ine njodzi isina musoro yekukuvadza hutano kana ishandiswa" nekuda kwenjodzi kuvashandi vanobatwa nekemikari zvakananga kana zvisina kunanga, vatengi vanoshandisa kemikari, uye vanhu vanobatwa nekemikari.
"Sainzi pamusoro pemethylene chloride yakajeka, uye kusangana nemethylene chloride kunogona kukonzera migumisiro yakakomba kuhutano uye kunyange rufu," akadaro Mutungamiriri weEPA Michael S. Regan mumashoko ake. Izvi ndizvo zvinoitika kumhuri dzakawanda dzakarasikirwa nevadikanwi nekuda kwechepfu yakakomba," akadaro. "Ndosaka Environmental Protection Agency iri kutora matanho nekukurudzira kurambidzwa kwekushandiswa kwakawanda kwekemikari iyi uye kuisa mitemo yakaoma munzvimbo dzebasa kuchengetedza hutano hwevashandi uye kuderedza kusangana nenjodzi munzvimbo dzese."
Chinangwa chekurambidzwa kwakarongwa ndechekudzivirira vanhu kubva panjodzi nekuderedza kusvibiswa nekubvumira kushandiswa kwemethylene chloride chete mumamiriro ezvinhu akatariswa zvakanyanya munzvimbo dzebasa, inodaro Environmental Protection Agency. Kugadzirwa, kugadziriswa uye kuparadzirwa kwemethylene chloride kuchamira mumwedzi gumi nemishanu inotevera. Muzviitiko apo chikumbiro chinorambidza kemikari, ongororo yeEPA yakawana kuti "zvimwe zvigadzirwa zvine mutengo wakafanana uye zvinoshanda ... zvinowanzo kuwanikwa."
"Kurambidzwa uku kwakarongwa kare kunoratidza kufambira mberi kukuru kwatakaita mukuisa dziviriro itsva dzekuchengetedza makemikari uye kutora matanho akanonoka ekuchengetedza hutano hweveruzhinji zviri nani," akadaro Regan.
Kerry Breen mupepeti wenhau uye mutori wenhau weCBS News. Mishumo yake inotarisa zviitiko zviri kuitika, nhau dzichangoburwa uye kushandiswa zvisina kunaka kwezvinodhaka.
